I have also used electric casing to label my plants. I'll bring it up as another tip soon. They too work very well. I just posted in another comment here about our environment. Do see that comment as I don't want to repeat here. "Slow down our waste contribution to the enviromnent." One of my friends 'awarded' me with the tag 'Master recycler'!! Not for nothing I have about 70+ items in my 'Junk blog'. If you like to see this, I'll link.
Thanks Bonnie.
